The aim of this paper is to report on an attempt to design and implement an intelligent system capable of generating the correct part of speech for a given sentence while the sentence is totally new to the system and not stored in any database available to the system. It follows the same steps a normal individual does to provide the correct parts of speech using a natural language processor. It...

A Side Lobe Canceller (SLC) structure is a conventional partially adaptive technique which is used in large adaptive array radars. If a desired signal has long time duration in comparison with the SLC adaptation time, signal components may be cancelled. So, this paper presents a modified SLC which eliminates desired signal cancellation problems and allows using an unconstrained adaptive algorit...

background: the inappropriate use of handouts and notes is a common academic problem among students. students' notes are too brief and incomplete in compare with references; hence they may not cover the required content for the courses. the aim of this paper is to analyze students' attitude toward reading handouts and notes instead of references. methods: in this analytical and descri...

editor’s note geopersia is published biannually by the college of science, university of tehran, iran. the college of science published “journal of science”, which covered all fields of basic science, from 1968 to 2010. it was then decided that the college’s journals should be more specialized, and hence publication of geopersia was launched. geopersia aims to publish peer-reviewed original res...

In this paper we suggest a method to calculate the first integrals of a special system of the first order of differential equations. Then we use the method for finding the solutions of some differential equations such as, the differential equation of RLC circuit.

herein, we present the case of a child with acute lymphoblastic leukaemia who simultaneously developed probable invasive aspergillosis and was diagnosed with gi mucormycosis by histopathologic examination. the patient referred to the pediatric intensive ca re unit of ege university due to clinical deterioration and severe lower gastrointestinal system bleeding. main symptoms were abdominal dist...

In this note, small amplitude free vibration of a double-beam system in presence of inner layer nonlinearity is investigated. The nonlinearity is due to inner layer material and is not related to large amplitude vibration. At first, frequencies of a double-beam system with linear inner layer are studied and categorized as synchronous and asynchronous frequencies. It is revealed that the inner l...
